Melting ice shelves around Antarctica control the massive input of freshwater into the ocean and play an intricate role in global heat redistribution. The Amery Ice Shelf regulates wintertime sea-ice growth and dense shelf water formation. We investigated the role of warm Antarctic Surface Water in...
29. Which effect of temperature increase on arctic ecosystems, will increase carbon dioxide in the atmosphere? B A Greater production of plants due to warmer temperatures and changing vegetation. B Greater decomposition of organic matter currently stored in permafrost. C Less ice and snow will cause...
BEIJING, Oct. 10 (Xinhua) -- China will double the frequency of Arctic expeditions to once a year from this year, the State Oceanic Administration (SOA) announced Tuesday. China's ice breaker, the Xuelong (Snow Dragon) returned to base in Shanghai Tuesday after 83 days on the Arctic rim...
Carbon cycle in the Arctic terrestrial ecosystems in relation to the global warming and methane (CH) concentrations increased markedly during the past few centuries. The increase in concentration of these greenhouse gases was coupled with ... J Fang,S Fei - 《极地科学进展(英文版)》 被引量: 47...
The report covers three topics: the impact of global land-cover change on carbon loss and carbon uptake, the global production of bulk grain and oil crops and the food security situation, and the changes and impacts of snow and ice in the Antarctic, Arctic and Qinghai-Tibet Plateau regions....
However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age".The findings appear in the journal Environmental Research Letters."We could get to the point where one-in-seven winters are very cold, as we...
Over the last 20years, the study area has been exposed to well-documented increases in air and sea temperature, increased windiness, and marked decreases in both the duration and extent of sea ice cover. The study revealed a twofold increase in the number of species found intertidally, a ...
